The contamination was really through a number of sources. The City of Belleville itself was one of the sources. Some of the lands were used as a landfill. This was back in a time in our collective past in this country where we didn't value waterfronts as we do today. Unfortunately, that was chosen as a landfill site. That was only one source.
Another source was the fact that the federally owned lands were used as a commercial working harbour. There were ships that came in that unloaded coal, that unloaded oil. Some of the federal lands were leased to oil companies that had tank farms on the property. Those activities resulted in contaminants leaching into the soil. So there were a number of different sources of those contaminants.
The fact that the city was part of that problem, if you will, is partly why I believe it's important that the city invest in the cleanup, which is what we have committed to do. It really was a problem caused by a number of different participants and users of the site.
